High-speed 5x4x0.9mm PIN Photodiode For Wearables

Vishay has rolled out a new high speed silicon PIN photodiode with enhanced sensitivity for visible light in a compact 5 x 4 x 0.9 mm SMD package. The new VEMD5080X01 is said to offer fast switching times and low capacitance for precise signal detection in wearable devices and medical, industrial, and automotive applications.

The photodiode’s small size and sensitivity enable slim sensor designs for optical heart rate detection in wearable devices such as fitness trackers and smart watches.

Claimed to offer a large radiant-sensitive area measuring 7.5 mm2 — and high radiant sensitivity with a reverse light current of 45 µA and dark current of 0.2 nA — the device detects visible and near infrared radiation over a wide sensitivity range from 350 nm to 1100 nm.

For green LEDs, the device’s sensitivity is claimed to offer a 30 % improvement over previous-generation solutions.

When used with Vishay’s VLMTG1400 green LED, the photodiode’s small size and sensitivity enable slim sensor designs for optical heart rate detection in wearable devices such as fitness trackers and smart watches.

When combined with Vishay’s VSMD66694 660 nm and 940 nm dual color emitting diodes, the device is ideal for SpO2 measurement in medical monitors.

In addition, it provides high speed photo detection in smoke detectors with dual-wavelength light sources and automotive dust and particle sensors in combination with a red diode.

The VEMD5080X01 features a ± 65° angle of half-sensitivity, a wide temperature range of -40 °C to +110 °C, and 950 nm wavelength of peak sensitivity. The robust device is tested to AEC-Q101 standards for Automotive Grade semiconductors.
